Abstract

The invention relates to a nozzle, preferably for use in sprinklers and spray heads, for spraying extinguishing medium, the nozzle comprising a housing (7), an inlet end (1) and a first conduit (2) leading from the inlet end to a nozzle opening (3) to enable the spraying of the medium through the nozzle. In order that the flow in the nozzle would grow notably with an increase in pressure, the nozzle comprises a second conduit (4) for spraying the medium from the nozzle, a valve element (6) loaded by a spring (5) being arranged in the conduit so as to keep the second conduit closed when the valve element is subjected to a first pressure by said medium, and the valve element being arranged to open said second conduit when the valve element is subjected to a second pressure by said medium, and the second pressure being higher than the first pressure. The invention also relates to a fire fighting installation in which nozzles of the above type are used and in which the pressure source is arranged to increase the flow of the extinguishing medium so that the power produced by the pressure source will not drop directly proportionally to a decrease in pressure.
